Pitching for a 14 gallon Biere de Garde

[LouBrew2]

I'm having trouble calculating on Mr. Malty. First, because I don't know if it's mandatory to use a starter for liquid yeast. Second, I don't understand how to adjust the growth factor. Thanks for the help in advance!

My estimated OG is 1.062 for a 14 gallon batch.

If you're making a simple starter you'd need a 4 liter starter with 4 packs or a 6 liter starter with 3 packs. If you're shaking it every hour or so, 2.4L with 4 packs and 3.5L with 3. If you have a stir plate, 1.5 liters with 4 packs or 2.25 liters with 3 packs.
